Current price is (bid or ask - does not matter)

The blue line gives you the price (which is written on a chart) above the current price

The red line gives you the price below.

I am tryiing to find them programmatically, as well as there keys, as the are a part of dictionary

alexander.n.fedorov
02 Nov 2018, 15:13

highsDict.Where(x => x.Value > MarketSeries.Close.Last(0)).OrderByDescending(x => x.Value).Last();

This one builds, but I do not know what to do with it. I need to find value (1.155)

I am not even concerned about the key

Thank you for reply, Panagiotis!

The code will bild if you take away the underscored row

That will give me the picture I posted

but I was trying to find it programmatically out of dictionary, and so far I could not

If you can, please help find programmatically the first price above (on a blue  line) and below (on a red line)

Hi Sasha,

1. You can use out keyword. 
2. A cBot cannot stop other cBots, at least in a direct way. If you could explain what you are trying to do, I could suggest something.

Best Regards,

Panagiotis

 

I think that I will study the link. Thank you.

For the second one , I think, that one of the bots (special bot) when stopped with send and SQL message to change the flag to "stop"

Every other bot OnTick or OnBar will check the flag (through the SQL connection) and if the flag says "stop"  it will stop.

I was just hoping that it is in an API, where Account.Algos.Stop or smth like that

Thank you and regards
Sasha
By the way, how do you right SQL statement  in LINQ?

Hi, Panagiotis. 
That is what i do, but means, I have to put the whole body of bot inside it

All right. Thank you

Hi Sasha,

OrderBy will not sort the original list/dictionary. It will return a new sorted instance.

Best Regards,

Panagiotis

Unfortunately, I do not know how to do that, so  I guess I will have to find a book and study
